Be it known that l, "Wimmer C. Heneoooli, a citizen oi the United Staines,Y residing at city of Si. Louis5 State of Missouri, have invented a eerfain new and useful Improve nient in Sixheel Trucks, of which Jdie 'lolloningf is a full, olea?, and exact description, such as will enable others skilled in the arl lo which it appertains to niake and use the same` reference beinghad to the aeeonipanyf ing drawings, forming parl; of ibis specificaL tion, in which-- Figure l is a partial plan view of my improved ear truck. Fig. 2 is a side elevational View parl-ly in section o-i said truck. Fig, 3 is a cross sectional View showing some oi lhe pai in elevation. N

'lhis'inve'nion rela'es to a new and useful iniiirovemenig .in ear trucks of "ehe six wheel lypo, die object being to 'reduce the Weig i i'he ruek and to provide a simple, strong and economical struetnre which will iulil all of zhe reqi-iirenients oi an eqnalizing sixivlioel ear zri'xela l'. is weil nown il equaliaing trucks are designed A ,'ieularly to compensate irregularities i 'lille' iael, he load beine distribniied beiveen ifhe three pairs oi.E wleels dirough the i ulality of equaliriug bars, li is init-,e peculiar arraneeinen oli these equalizing bars and the 1 mounting' them in die truck side frame and i'he relation oli said bars 'to-each other and 'lo :ehe hree gairs o wheels ihai. :lorin folie essence of my present ii niion.

The casting is meunier. or down the noriY liia. The nel" above the journal the inner dov inrned en( ing ,i ar directly upon at 9 at or near lthe ouler and preferably upper ends of the journal side frame, said equalizing bars preferably lying` partially Within and partially Without the channels of the side frame. ln J(he drawing l have shown the outer ends of the equalizing bars being` provided With pedestal jaws 8a but it will be ,readily nndersrood that the journal boxes 10 which receive the ends or' the axles l may be attached to the outer ends of the equalizer bars in any suitable or Well known manner, or, if desired said boxes may be cast integral with said equalizer1 bars.

il indicates column guides extending downwardly from the ends of the side irazne, .the lower ends of these column guides beingl connected by a spring bolster support which may be integral, as shown, or in the form' of a removable piece'7 as desired. W here an integral spring support is used, 1bhe space between the column guides is .widened at its lower portion to permit the introduction and removal of the bolster in ille manner now commonly employed. The spring support is provided willi lugs l2 around which the bolster springs 13 are arranged, the lugs l2 centering said springs and preventing; their displacement.

lll indicates the holsters which may be of any ordinary or approved eonsiiruetion and which bolsers are. connected by an X-shape easiing l5A carrying the Center plate 16. T he @nds of the )(-sliape member l5 may Abe aliaehed to the holsters in any suitable manner or, if desired, said member and the holsters may be formed integral. The outer ends of 'die bolsl'ers are also pr 'erably connected by an arhed barvl7, on which the' side bearing may be Carried.

ln operation, Iit will be observed thai: ille load iransmilted ifo the holsters lhrouggli die eenier plate or the side bearings bolste' arched bars and thaiy the bola urn are supported by `the bolster springs al' the ioni' ernners of the truck.

The eoualizing'bars have their ends bearing upon (or Carrying) ehe jourboxes in which the axles of the 'three ws of Wheels are n'iounled.

In this manner the load is evenly distributed over the three sets of axle boxes, and, furthermore, the car body is yieldingly supported by the bolster spring. If desired, the X-shape fra-me carrying the center bearing could be suspended from stirrup hangers carried by the bolsters'in a manner well known in swing vmotion trucks, or the said X-shape frame could be supported-on rollers for the purpose vof having limited lateral movement as is commonly employed in the Well known Barber type of truck.

2. In a car truck, a truck side frame havlng a journal box capable of movement therein, an equalizing bar pivotally mounted upon said side frame in a horizontal plane above said journal box and having one end bearing upon said journal box, and another journal box carried by the opposite end of said equalizer bar the movement of said last mentioned journal box being in an arc' of a circle about the pivotal point of the equaliziiig bar.

3. In a car` truck, the combination of a truck side frame, a journal box slidingly carried thereby at or about the center of said frame, equalizing bars pivotally mounted upon said frame in a horizontal plane above said journal box and having their ends bearing upon said journal box, and jo-urnal boxes carried by the outer ends of said equalizing bars, the-movement of said journal boxes being in arcs ofvcircles about lthe pivotal points of said equalizing bars.

t. In a car truck, the combination of a U- shape truck side frame, pedestal jaws connected thereto, a journal box slidinglymounted between said pedestal jaws, equal- .izing bars arranged partially within `the channel of said side frame and pivotally mounted at or near the ends thereof, and journal boxes carried near the outer ends of said equalizing bars.

5. In a car truck, the.. combination of a truck side frame having pedestal jaws and column guides, a journal box slidingly mounted in said pedestal jaws, holsters yieldingly supported within said column guides, and equalizing bars pivotally mounted upon said side frame and carrying journal boxes at oneend thereof.

. 6. A truck side frame substantially U-shape in cross section having pedestal jaws depending therefrom at about its middle portion, and a pair of column guides depending therefrom at each end.4

7. A truck side frame substantially U-shape in cross section having pedestal jaws depending therefrom at about its middle portion, and a pair of column guides depending therefrom at each end, the space between. each pair of column guides being widened at the lower portion thereof.

8. A. truck side frame substantially U-shape in cross section having pedestal jaws depending therefrom at'about its middle portion, and a pair of column guides depending therefrom at each end, each pair of column guides being connected at their lower ends, said connecting portions having lugs or teats having coperation with the bolster springs.

9. In a 4six wheel truck, a side frame, two pairs of. bolster guides formed integral therewith, and an integral member connecting the lower ends of each pair 'of bolster guides. y

10. In a six wheel car truck, a side frame, two pairs of bolster guides formed integral therewith, and a horizontally disposed member connecting the lower ends of the members of each pair of bolster guides.
